1. SAFETY NOTICES
Install the R-MAG®breaker within the design limitations as described on its nameplate and in
these instructions.
Follow your company’s safety procedures and all applicable laws, regulations and standards
whenever the equipment is being installed, operated, maintained and/or repaired.
WARNING:
FOLLOW THE INSTRUCTIONS IN THIS MANUAL AS WRITTEN. ANY FAILURE TO
DO SO MAY RESULT IN DEATH OR SERIOUS BODILY INJURY
This breaker should not be used as the sole means of isolating a high voltage circuit. For the
safety of personnel performing maintenance operations on the breaker or connecting equip-
ment, all components should be electrically disconnected by means of a visible break and
should be securely grounded prior to working in the high voltage or low voltage compartment.
This product is intended to be operated and maintained by qualified persons, thoroughly trained
and knowledgeable of the hazards involved. This publication is written only for such qualified
persons and is not intended to be a substitute for adequate training and experience in the safety
procedures for this device.
WARNING
Detailed descriptions of standard repair procedures, safety principles and service operations are
not included. It is important to note this document contains some warnings and cautions against
some specific service methods that could cause personal injury to service personnel, damage
equipment, or render it unsafe. These warnings do not cover all conceivable ways in which serv-
ice, whether or not recommended by ABB, might be performed or the possible hazardous
consequences of each conceivable way, nor could ABB investigate all such ways. Anyone using
service procedures or tools, whether or not recommended by ABB, must satisfy himself

5
thoroughly that neither personal safety nor equipment safety will be jeopardized by the service
method or tools selected.
All information contained in this manual is based on the latest product information available at
the time of printing. The right is reserved to make changes at any time without notice.
2. INTRODUCTION
These instructions do not attempt to provide the user of this equipment with every possible diffi-
culty that may occur in the application, operation and maintenance of the product. Also, as
improvement in parts and assemblies are made, some parts may differ in appearance as depict-
ed in the illustrations; however, functionality will be equivalent.
The Type R-MAG breaker is a high-voltage, three-phase device incorporating three vacuum
interrupters, gang operated by a magnetic actuator. Together with the optional relaying and
current transformers, the breaker will sense an overload and automatically open.
Satisfactory performance of the breaker is contingent upon correct installation of the breaker,
and adequate maintenance and service of the breaker. Careful study of these instructions will
permit the user to obtain maximum benefit from this device.
3. RECEIVING, HANDLING AND STORAGE
Each breaker is assembled and tested at the factory prior to shipment.
This equipment was packed and shipped in factory new condition. If damage is noted, call the
carrier at once for inspection and request an inspection report. File a formal claim with the carri-
er, supported with paid freight bill, inspection report and invoice. The local ABB Sales Office
must be notified. This must be done within 10 days of receipt or receiver assumes all
responsibility for damage.
3.1 Receiving Inspection
Upon receipt, it is important to inspect promptly to be certain that the correct material has been
received. In case of shortage, immediately notify the local ABB Sales Office.
Check all parts against the shipping list as they are unpacked. Instructions and literature packed
with the breaker should be kept with the unit. The cabinet provides a convenient place to keep
this instruction book, a copy of the schematic, connection diagram and the breaker test report.
Additional copies of these documents may be obtained upon request from the local ABB Sales
Office.
If the breaker is not to be placed in service immediately, it is essential that proper care be exer-
cised in the handling and storage to ensure good operating conditions in the future. (see section
3.3 Storage)
3.2 Handling
The R-MAG breaker comes with two brackets attached to the sides of the cabinet which provide
for lifting the breaker. A two-point lift is recommended using these brackets. (see Figure 2 Lifting
Detail)
